Thanks guys.
The tires are Carlisle, 26".
Got into checking everything out today... Boy, udder disappointment.
For starters got the tractor up on my hoist and I figured I'd check out the starter (remember my 782 with the loose starter breaking the mounting tab off the block) and guess what I found? Another starter replaced and only one nut used to attach it, so had to fiddle around getting the lower nut on. They also butchered up the tin around it getting the starter in.

some peples kids.
Noticed a pretty good oil leak behind the PTO, so figuring it was the seal, I began to take off the PTO to access it and broke two rusted studs off the field coil.....

Went into town to get a seal from my dealer and proceeded to tell him about the tractor, and he was like, boy that machine sounds familiar. REALLY!!!
So come to find out the PO fed me a pretty good story.... The dealer had the tractor in his shop earlier this year. The PO brought it to him because he couldn't get it to run. It had a blown head gasket and a "huge" amount of mouse house going on. So he did what the PO wanted, cleaned out the mouse house and installed a head gasket, and got it running. But he (dealer) also told me it's got a miss, and the PO didn't want to spend anymore on it to find out what the problem is.
So that's part of the story. Then I noticed today when I got the tractor up in the air to work on, it's got oil leaks O'PLENTY!! It has a pretty good miss in the engine I didn't notice outside by the PO's house, but notice it in my shop. Hearing isn't what it used to be, especially outside. Plus at a little disadvantage when it comes to looking under it while it's got all it's feet on the ground.

Nobody's fault but my own.
So at this point I don't know what I'm going to do. Looking right now like a money pit. Might just fix what "really" needs it and punt it down the road.

But,,,, here's my problem. I can't screw somebody either, because I don't like the feeling of getting screwed and not being kissed

.
Don't know...But I do have a question. Can a field coil be welded on would it mess it up? Thinking of tacking in two fine thread bolts to replace the rusted broken studs. It'll work, but don't know if welding will fry the field coil.
Sorry so long winded, just guess I wanted to vent. Now I'm going to bed with a jar of Vaseline, cause I got this burning feeling down there if you know what I MEAN!
